The MC3479 is designed to drive a two–phase stepper motor in the

bipolar mode. The circuit consists of four input sections, a logic

decoding/sequencing section, two driver–stages for the motor coils, and an

output to indicate the Phase A drive state.

STEPPER MOTOR

DRIVER

• Single Supply Operation: 7.2 to 16.5 V
